We have no idea of the excellency, beauty, harmony and symphony of the music in the heavens.

 We have no idea of the excellence of the music we shall have in heaven. It may be said of that, as one of the Apostles has said in relation to something else—“Eye hath not seen, nor ear heard, neither hath it entered into the heart of man to conceive of those things which are prepared for those who love and fear God.” [See 1 Corinthians 2:9.] We have no idea of the excellency, beauty, harmony and symphony of the music in the heavens.

Could you gaze into heaven five minutes, you would know more than you would by reading all that ever was written on the subject

Could we read and comprehend all that has been written from the days of Adam, on the relation of man to God and angels in a future state, we should know very little about it. Reading the experience of others, or the revelation given to them, can never give us a comprehensive view of our condition and true relation to God. Knowledge of these things can only be obtained by experience through the ordinances of God set forth for that purpose. Could you gaze into heaven five minutes, you would know more than you would by reading all that ever was written on the subject. … I assure the Saints that truth … can and may be known through the revelations of God in the way of His ordinances, and in answer to prayer.”
